RESULTS AND DISCUSSION 
The effectiveness of the compounds used was evaluated by the size of the 
eaten area in percent relative to the length of the traps. These indicators are used to 
determine the effectiveness of the compounds and are shown in the form of 
diagrams (Fig. 9-12). Statistical processing and correlation analysis of the obtained 
data were performed using the GraphPadPrism 8.0.1 software. 
To establish the biological activity, 0.2% of the concentration of the following 
substances were selected: 2-naphthalenemethanol, 2-phenoxyethanol, triphenyl 
phosphate, sodium salt of N-hydroxynaphtholimide, sodium salt of naphthol-5-
sulfonic acid, ethylene glycol monobutyl ether, diethylene glycol monobutyl ether 
and phenol. Each trap containing bait, substances were buried in the soil for a 
period of 3, 7, 10, 30 days.

ig. 9. Phago-stimulating effect of compounds by day of registration 
Considering the activity of the first group of compounds shown in Fig. 9, one 
can notice that their phago-stimulating effect on the third day has almost the same 
attractive effect, with the exception of ethylene glycol butyl ether. 
After the seventh day, the activity of all the selected compounds had the same 
activity, which increased dramatically (5 times) compared to the third day of 
testing for the compounds: 2-naphthalenemethanol, 2-phenoxyethanol and 
diethylene glycol butyl ether. 
Ethylene glycol butyl ether was 1.7 less weaker than these three indicators. A 
high activity index on the 10th day of testing is inherent for ethylene glycol butyl 
ether. The activity of the remaining compounds decreased on going from 2-
phenoxyethanol to butyl ether of diethylene glycol and 2-naphthalenemethanol. 
The 30th day of research was the highest for the traps containing ethylene glycol 
butyl ether, the phago-stimulating effect of which was almost 2 times higher than 
that of 2-naphthalenemethanol, and 1.5 times higher than that of 2-phenoxyethanol 
and diethylene glycol butyl ether, respectively.
